In reply to Petarghh:
Can get windy for sure. Seen quite a few tents trashed there.
Facilities are basic (or were when we were there a couple of years back) - showers pretty poor and only one hot tap for the entire site.
Stayed in the "bunkhouse" there once, and althought the owners were very helpful and friendly, I've never gone back.
Gwern Gof Uchaf down the road is just as windy, but the facilities are a lot better.
